I agree; you do not need a religion to teach you good and evil or a person telling you what to do. I have friends who are Atheists who are some of the kindest people I know.
My grandmother grew up without ANY religion. She had no idea what Christianity was, not to mention Paganism. Religion was simply not a topic in their home. I do remember many years ago when I was very young we were driving down the road, we passed this large, straight, beautiful pine tree; with the top completely missing.
She told me that when she was a little girl that her family was extremely poor, their parents barely had enough money to even feed them.
They did, however celebrate the typical 'christmas', but it had no religion behind it. They passed the few presents they had and they had a tree. This one year however, they could not afford a tree. Her dad badly wanted the kids to have a tree to decorate. One night they all went out and found this small pine tree growing off the side the road on someone else's property and they cut it down. I remember my grandmother telling me that even though her family was happy to get a tree, the somehow, deep inside her, she knew that for some reason it was wrong.
And you can compare that tree to a person; even though part of it was missing and taken away; it still continues to grow straight and tall and magnificent; with another pine tree next to it. I think; no matter someone's religion or lack of, people are born with decency and can do good, and find happiness. It makes me sad that people say otherwise and force beliefs on judgment on others.. Life should not be about converting others and making them see your point of view. It should be about finding your own happiness...
So yes, I believe "People are born with all the potential skills they need to make moral and ethical judgments."
That said; I also (personally) believe the universe and dieties are always around and can guide you to do the right things and be a good person.
(I might say, that my grandmother eventually married, was converted, and became Christian, with most of her family following, however, had there been Pagan beliefs around and available to learn from - who knows.
